Description

The PCM512x devices are a family of monolithic CMOS-integratedcircuits that include a stereo digital-to-analog converter and additional support circuitry in asmall TSSOP package. The PCM512x uses the latest generation of TI’s advancedsegment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clockjitter.

Members of the PCM512x family integrate preset audio processingfunctions with programmable coefficients, allowing developers to change the characteristics of theinterpolation filter, speaker EQ, dynamic range controls, and average volume control in theirproducts.

The PCM512x provides 2.1-VRMS ground-centeredoutputs, allowing designers to eliminate DC-blocking capacitors on the output, as well as externalmuting circuits traditionally associated with single supply line drivers.

The integrated line driver surpasses all other charge-pump-based line drivers bysupporting loads down to 1 kΩ. By supporting loads down to 1 kΩ, the PCM512xcan essentially drive up to 10 products in parallel (LCD TV, DVDR, AV receivers, and so forth).

The integrated PLL on the device removes the requirement for a system clock (commonlyknown as master clock), allowing a 3-wire I2S connection, along withreducing system EMI.
